Multi-Dimension Logarithmic Number System Digital Filter Bank

A new filterbank processor algorithm for a digital hearing instrument based
on the Multi-Dimensional Logarithmic Number System (MDLNS) with a low power
structure. The processor has integrated binary to MDLNS converters. The design
has been optimized for timing; testing shows very competitive power comsumption
and area requirements to current binary filter banks. Implemented on TSMCs
0.18Ám CMOS process.
